I have made a Blaze spawner farm, that collects blazes, in a small area where the player can manuel kill them and its automatic collect the loot. The player will not be attacked, while using it.

I suggest you use a Looting III, Mending, Sweeping Edge III, Shapness V and Unbreaking III sword

I havn't seen a design like this, but i think there is.

It's a simple design which contains two Ethos hopper clocks and two flying machines basicly.
